How can I parse integers from a string in Java?

Question

I need to retrieve out the nominator and denominator into two int type variables, from a string. It could be: "1/-2", "4 /0", "-2/ 1234", or " 5"(in this case the denominator is 1);

There might be spaces between the integers and "/", no spaces inside a integer. And there might be only one integer in the string and no "/".

Any ideas? Thanks.

Hi, I combined your guys' answers, and it works! Thanks!

s is the string

s = s.trim();
String[] tokens = s.split("[ /]+");
int inputNumerator = Integer.parseInt(tokens[0]);
int inputDenominator = 1;
if (tokens.length != 1)
    inputDenominator = Integer.parseInt(tokens[1]);

Solution

String[] parts = s.split(" */ *");
int num = Integer.parseInt(parts[0]),
    den = Integer.parseInt(parts[1]);
